AFi-II 12 and AFi-II 10 backs have got tilt screen and rotating sensors
80MP and 56MP have different pixel size an sensor shape. Being 2 yrs newer, the 80MP uses an updated sensor design
I am an architectural shooter and use a Sinar e75 back on a technical camera. When I purchased the back it was supplied with a "birth certificate" measuring the 4 corners and the center of the sensor and the maximum variation was 6-7 one thousands of a millimeter. Using Rodenstock HR lenses I frequently have to shoot wide open @ f4.5 getting excellent results with regard to edge to edge sharpness.
Now.....reading this forum, one would have the impression that focus is a big problem that can not be accurately resolved without the use of
various solutions offered by different manufacturer's of technical cameras and/or digital backs: laser or sonar measuring devices, HPF focus rings, adapter plates with adjustable shims, esoteric helical focusing mounts, live view, and focus indicators on the lcd using contrast......
Does Leaf provide this type of a factory "birth certificate" measuring the variations of the perpendicularity of the sensor and how the heck do you maintain this on a sensor that rotates internally? Will I have to stop down the Rodie HR's to get a sharp photograph?
Can you also explain the "updated sensor design" of the 80MP back versus the 56MP?
